That is because the plastic container does not contain water. Current microwaves use a wavelenghts that is absorbed by water, therefore transmitting its energy to water molecules contained in the food, but not in the plastic container that contains the food.
Tupperware is made from high density polyethylene [HDPE] and depending on several other factors, will melt at around 278 F [137 C]. The melting point of polymers like HDPE is not like ice melting to water -- which is indicative of a sharp phase change.
In general, paper products, aluminium, polyethylene terephthalate (PETE), and polystyrene (PS) should never be used in the microwave. On the other hand, high-density polyethylene (HDPE), polypropylene (PP), and molded fiber & bagasse are typically safe to be microwaved.
